The output of '0/Block#{number}' from uhd_usrp_probe for out-of-tree
blocks in UHD 4.0 is a known limitation and expected. When UHD
discovers the topology of the RFNoC graph, it can see that a block is
there, but because it isn't registered with UHD, it is display with
the unimaginative name of 'Block'. Normally, the block controller
class contains the code to register the block with UHD; only in-tree
blocks that are built as a part of UHD have their names displayed in
uhd_usrp_probe.
